This paper presents a platform for developing, testing and executing synchronous collaborative applications in a distributed, heterogeneous environment. Even though several environments exist nowadays, specific problems are not treated satisfactorily. Especially in ‘real’ network environments, problems like unstable network connections and low bandwidths have to be considered.The DreamTeam platform addresses the special needs of environments with non-optimal characteristics which can, be found in distance learning scenarios. DreamTeam comprises a development environment, a simulation environment and a runtime environment; it is based (...) upon the concept of a fully decentralised architecture and encourages rapid prototyping.DreamTeam supports developers of shared applications through a component concept. Using components helps to divide a software project into well-defined parts. Well-documented interfaces help to reduce integration efforts and improve software quality. A selection of sample applications with DreamTeam validates our design concept. (shrink)

Frequent public uproar over forms of data science that rely on information about people demonstrates the challenges of defining and demonstrating trustworthy digital data research practices. This paper reviews problems of trustworthiness in what we term pervasive data research: scholarship that relies on the rich information generated about people through digital interaction. We highlight the entwined problems of participant unawareness of such research and the relationship of pervasive data research to corporate datafication and surveillance. We suggest a way forward by (...) drawing from the history of a different methodological approach in which researchers have struggled with trustworthy practice: ethnography. To grapple with the colonial legacy of their methods, ethnographers have developed analytic lenses and researcher practices that foreground relations of awareness and power. These lenses are inspiring but also challenging for pervasive data research, given the flattening of contexts inherent in digital data collection. We propose ways that pervasive data researchers can incorporate reflection on awareness and power within their research to support the development of trustworthy data science. (shrink)

Leibniz was probably the last universal scholar in modern times who made original and innovative achievements in all the essential fields of knowledge of his time: as a reform-oriented lawyer, a multilateral thinking diplomat, as a mathematician of infinitesimal calculus, as the inventor of a calculating machine and in the mining of horizontal wind power, as an organizer of science and as one of the first historians who strived for source-critical methodical objectivity. However, this baroque diversity can only be understood (...) from the center of a monadological philosophy, which wants to establish the unity of scientific worldview and metaphysical concept of the world. It is distorted in the classical reception because only Leibniz the Theodicy was known. The topicality of Leibniz today consists in re-exposing the original basic idea of unity in diversity and asking how it can be made fruitful for philosophical and political thought in the 21st century. This book is a translation of the original German 1st edition Leibniz und die Folgen by Jörg Zimmer, published by J.B. Metzler, imprint of Springer-Verlag GmbH, part of Springer Nature in 2018. The translation was done with the help of artificial intelligence. A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors. (shrink)

Whereas the Upanishads contain much which is, strictly speaking, of little interest to the historian of Indian thought, the Pre-Upanishadic texts are not completely devoid of passages which are of special importance for anyone who endeavours to trace the origin and oldest form of the main texts of classical Indian philosophy. Too often the difference between Upanishads and Pre-Upanishadic literature has been exaggerated ; too often the philosophical importance of the ritualistic speculations contained in the Brahmanas has been undervalued ; (...) too often these texts have been neglected by the compilers of handbooks. One of those points which have not always received due attention concerns the theoretic foundation of the belief in the possibility of gaining the victory over death and of the efforts to realize this ambition. One of the most important problems in which the Indians have always been interested is the relation between the One and the Many, between this phenomenal world and its source and ground. Already in the Rgveda opinions differ : it has been a divine architect who made the phenomenal world ; it has been an anonymous primeval deity who became a golden germ from which a demiurge was born ; the world has arisen from the impersonal One who desired to create the world, etc. In the course of time these creators and ideas of the original One fused into the great figure of Prajapati, „the Lord of Creatures”. This God, who occupies a central position in the Brdhmawa-texts originally was what he was to remain in popular belief : the deity presiding over biological creation. In the ritualistic speculations of the authors of the Brahmanas he is the Creator, the Father of gods and anti-gods, the origin of creation. In the beginning Prajapati was alone, he was ,all this’, he was the universe in ,concentrated’ and unmanifested form. By way of emanation and self-differentiation he became the manifested universe, including the creatures. After this creative activity he is empty and exhausted, because he has ,entered the universe' or rather transformed himself into the universe. His strength, force and health can however be recovered and restored by means of rites. The world and the creatures which emanated from Prajapati were not perfect ; they were a discontinuum, disintegrated, in the power of death. In order to make life possible and to make the world habitable Prajdpati instituted rites. Prajapati is in the Brahmanas identified with the highest and most general categories ; he is the year, i.e. the complete cycle of time comprising the past and the future, totality and completeness. The year, viewed as an integral structure is the fundamental basis of all that happens. Being also the rite, the sacral act, Prajapati is on the other hand the earthly counterpart of the great cosmic drama. On these two identifications the ritualistic system of these authors is constructed. Among these authorities Sandilya. occupies a prominent place. The mundane events oscillating between the poles of birth and death, of genesis and decay, rites are needed to reintegrate what has become decomposed. They are however also to restore the original unity and totality, to co-ordinate the non-co-ordinated phenomena, to reconstruct Prajapati, to restore his original oneness. The rites reduce, temporarily it is true and with regard to the individual who has them performed, the phenomenal multiplicity to a reintegrated totality, in which the diversity of Prajapati's emanation has been destroyed, and the original unity and oneness has been restored. This theory underlies the structure of the great Fire-altar , by which the sacrificer identifies himself with Prajapati whose original unity is restored. By performing this elaborate ritual the personality of the sacrificer was transformed into a new and divine existence, which was no longer subject to the imperfections proper to this world. That is to say : the sacrificer acquires ,immortality' , he transcends the limits of phenomenal time, he becomes sarva, i.e. safe-andsound, whole. Prajapati-the year will not destroy the man who identifies himself with the totality, with Prajapati-the year, and who has acquired an insight into the meaning of this identification ; that man overcomes disintegration and discontinuity, he gains the victory over death, that is to say : he attains to a sound and complete condition. In the course of time the personal Prajapati and the impersonal Brahman are identified. In the early Upanishads the latter becomes the great fundamental principle. These works resume on the one hand ancient speculations a part of which has been preserved in the Rg- and Atharvavedas, and utilize, on the other hand, the ritualistic theories of the Brdhmawas. The tendency of their authors is however to dissociate themselves from ritualism. Emphasizing the quest for the salvation and spiritual welfare of the individual they go into the problem of the ,Soul' , that is the ,self' or the very core of the personality, which is essentially different from all phenomenal plurality. The hitman is identified with the Punira, the primeval man out of whom the universe arose. It follows that the Atrmn is also cosmic. According to Udddlaka Arum it is the subtle essence of all that exists. All the important potencies in the universe are said to be its manifestations. However, in these works . Htman and Brahman tend to fuse and the great teacher Ydjwavalkya concluded to their being identical. Ordinary men do not understand this identity, but the few who are able to arrive at this highly important insight gain the victory over the imperfections and contingencies of empirical existence. They experience the ecstatic and unanalysable condition of unity, the undifferentiated Plenum or Totality, the ,All'. They know that they are truly Brahman or Sarvam. Now, it is most important to attain to this condition, which implies the victory over death, before one is to die the worldly death. The man who dies without having escaped death will die again and again in the hereafter. Whereas the ritualists attempt to protect themselves from this much feared ,repeated death' by means of rites, especially by the construction of the Fire-altar, the teachers whose words are recorded in the early Upanishads ascribed the delivering power to the esoteric knowledge of the ,under lying theory', to the knowledge of the ritual-cosmic interrelations : the man who knows the relevant speculations will be released. This belief in the redeeming power of the rites and the ,theory' on which they are based was also of special importance with regard to the development of the Karman-doctrine. Thus ritual and spiritual identification with the One which is the Totality, the Primeval Being, the Creator, the Atman enables man by experiencing a transformation to conquer phenomenal time and death.

We study the problem of existence and generic existence of ultrafilters on ω. We prove a conjecture of $J\ddot{o}rg$ Brendle's showing that there is an ultrafilter that is countably closed but is not an ordinal ultrafilter under CH. We also show that Canjar's previous partial characterization of the generic existence of Q-points is the best that can be done. More simply put, there is no normal cardinal invariant equality that fully characterizes the generic existence of Q-points. We then sharpen results (...) on generic existence with the introduction of $\sigma-compact$ ultrafilters. We show that the generic existence of said ultrafilters is equivalent to $\delta = c$ . This result taken along with our result that there exists a $K_{\sigma}$ non-countably closed ultrafilter under CH, expands the size of the class of ultrafilters that were known to fit this description before. From the core of the proof, we get a new result on the cardinal invariants of the continuum, i.e., the cofinality of the sets with $\sigma-compact$ closure is δ. (shrink)

Religionsphilosophie hat sich nach Jörg Splett mit einer Fundamentalfrage zu befassen: Woher stammt die Idee des Guten, deren Sollensanspruch den Menschen unmittelbar trifft und ihm als Grund zur Mitliebe und Dankbarkeit aufleuchtet? Die vorliegende Festschrift zum 80. Geburtstag des Jubilars versammelt Beiträge im Spannungsfeld von Vernunft, Glaube und Liebe, die den Menschen in welthaften Symbolbeziehungen – z. B. des Spiels, der Ehe, der Personalität, der Individualität, des Mutterseins, der Theodizee, der Sinnfrage, der „Grenze der Sprache“ und der Suche nach Transzendenz (...) – denken. Im Mitlieben der Welt symbolisiert sich der Ursprung des Guten. (shrink)

There are many alternative ways that a mind or brain might represent that two of its representations were of the same object or property, the 'Strawson' model, the 'duplicates' model, the 'synchrony' mode, the 'Christmas lights' model, the 'anaphor' model, and so forth. I first discuss what would constitute that a mind or brain was using one of these systems of identity marking rather than another. I then discuss devastating effects that adopting the Strawson model has on the notion that (...) there are such things as modes of presentation in thought. Next I argue that Evans' idea that there are 'dynamic Fregean thoughts' has exactly the same implications. I argue further that all of the other models of thought discussed earlier are in fact isomorphic to the Strawson model. a search for the source of these difficulties reveals the classical notion of modes of presentation as resting on two assumptions, neither of which I recommend. It depends on denying that the way the mind reacts to or understands the thoughts or ideas that it harbours has any bearing on their intentional contents. And it depends on an internalist view of thought content, in particular, on denying that the natural informational content carried or potentially carried by a thought has any bearing on its intentional content.
